Molecular modeling of substrate binding in wild-type and mutant Corynebacteria 2,5-diketo-D-gluconate reductases

Khurana, S.; Sanli, G.; Powers, D.B.; Anderson, S.; Blaber, M.; Proteins 39, 68-75 (2000)

Data extracted from this reference:

Engineering
Amino acid exchange
Commentary
Organism
F22Y
the mutation causes a 2.5fold decrease in Km for 2,5-didehydro-D-gluconate whereas the value of kcat remains essentially unchanged
Corynebacterium sp.
Q192R
the mutation primarily affects the kcat parameter toward the 2,5-didehydro-D-gluconate substrate, increasing its value approximately 2.5fold, whereas Km is relatively unaffected, or increases slightly
